Verfahren zur Sollpositionsvorgabe eines Kolbens als Funktion der Stellung des Rotors eines Kolbenmotors

摘要

Instrument transformers furnish a sinusoidal signal corresponding to the angle of rotation of the crankshaft and a substantially linear signal corresponding to piston position. The difference between the two signals is applied to a phase sensitive detector, whose output activates inlet and outlet valves adding or subtracting hydraulic fluid constituting the linkage between the crankshaft and the piston, depending upon the polarity and magnitude of the output signal from the detector.
